Non-linear Observer of Single-rotor Single-flow Jet Turbine Engine during Operation
نویسنده
چکیده
The paper presents a type of observer based on reduced to minimum set of engine parameters measured directly: turbine-compressor rotational speed, engine inlet air pressure and temperature and atmospheric pressure. Results of application in analysis of data recorded during engine operation in non-stationary states of SO-3 engine (powering TS-11 Iskra aircraft) are presented. Possibilities of this observer practical application in turbine engine parameters degradation monitoring during operation are also discussed. Proposed method of jet turbine engine’s parameters degradation was not verified during real operation of an engine. Following actual knowledge, it should be verified scientifically. The easiest way is to use data from operation of a specific SO-3 engine.

Assessment of various rotor tip geometries on a single stage gas turbine performance
Tip leakage loss introduces major part of losses of the rotor in axial gas turbines. Therefore, the rotor blade tip has a considerable effect on rotor efficiency. To understand the flow physics of the rotor tip leakage, we solve the flow field for different tip platforms (passive flow control) and by considering coolant tip injection (active flow control). Various blade tip configurations s...
متن کاملApplication of guide blades for improving performance of savonius wind turbine
Application of guide blades is an appropriate method for improving aerodynamic performance of savonius wind turbine. Guide blades gather the wind energy around the turbine and guide them into the concave side of savonius rotor. In this paper, numerical investigation is conducted for evaluating effect of the guide blades on the performance of savonius turbine. Aerodynamic performance of the turb...
متن کاملSingle Crystal Turbine Blade Inspection Using a 2d Ultrasonic Array
In this paper a non-destructive method for inspecting jet-engine turbine blades for root cracking is developed. This method utilises 2D ultrasonic arrays to enable the detection and characterisation of sub-surface cracks in three-dimensions. The majority of modern turbine blades are manufactured from single crystals of nickel based superalloys which exhibit high elastic anisotropy. This complic...
متن کاملObject Strikes , Complete Loss of Thrust Were Leading Causes of U . S . Turbine - engine Helicopter Tail - rotor Accidents , 1988 Through 1993
All single-rotor helicopters require an antitorque device (usually a tail-rotor system) to counter the fuselage’s reaction to the rotation of the main-rotor system. From 1988 through 1993, there were 74 U.S. civil turbine-engine helicopter accidents involving the helicopter’s tail-rotor system, according to statistics from the U.S. National Transportation Safety Board (NTSB) and the U.S. Federa...
متن کاملIntegrated RANS/LES Computations of an Entire Gas Turbine Jet Engine
The interaction between different components of a jet engine represents a very important aspect of the engine design process. Sudden mass flow-rate changes induced by flow separation and pressure waves, interaction of the unsteady wakes originating from the fan blades with the low-pressure compressor, high temperature streaks interacting with the first stages of the turbine are all complex unst...
